You've obviously been very lucky in your private life, as I have, but I know plenty of people who haven't, and for that reason have sought affection, harmony and yes love in a new relationship including my own children, who are now both happy in new relationships. I certainly don't approve of infidelity for its own sake, but in certain circumstances it is perfectly understandable and actually desirable, unless you are advocating staying, as people, particularly woman were once forced to do, in a relationship that is deeply unhappy, perhaps violent, soul destroying and worse, just for the sake of 'doing the right thing'. Diana committed infidelity way before Charles went back to Camilla. She had multiple affairs,breaking up at least two marriages, Charles went back to the one woman he truly loved and has been married to for 17 years without a breath of scandal. They deeply love each other, who on earth could deny them that.
